For a detailed overview of how the various faults are acknowledged, please refer to the
SIMOCODE-DP manual, chapter 5.2, p. 5-4.
4.1.15 Additional Functions
This block provides two additional outputs QADD_F1 and QADD_F2 which can be controlled and
monitored. Operator control is through inputs ADDF1 and ADDF2, and operator enabling is
performed through the two inputs ADDF1_EN and ADDF2_EN (QADDF1OP and QADDF2OP).
These additional functions do not aect the internal block functions, and can be used for
controlling any of the binary signals.
4.1.16 Startup Response
After CPU startup (restart), the current statuses for LOCAL/REMOTE, MANUAL/AUTO, MANUAL
OPERATOR/MANUAL LINKED are retained. Commands are not output again. Depending on the
congured SIMOCODE-DP error response, a CPU STOP either causes a SIMOCODE-DP fault
(default setting), or (if "response PLC-CPU fault: retain status" is set) causes the current mode
status to be retained.
After startup, the number of cycles congured in the RUNUPCYC block I/O are inhibited.
4.1.17 Time-related Characteristics
The block must be called through a watchdog interrupt OB. The block sampling time is set in
parameter SAMPLE_T.
4.1.18 Bumpless Changeover
A command is reset in the block if the associated check-back signal is present. Consequently,
operating inputs ON1_OP, OFF_OP, and ON2_OP do not have to be tracked.
However, mode selections REMON_OP, AUTON_OP, and MANON_OP are always tracked in the
active settings.
4.1.19 Error Handling
For arithmetic program errors, ENO=0 or QERR=1 are set.
4.1.20 Messages
The SIMO_CHN block uses the Alarm_8P block for generating messages.
